Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 The implementation flow of the product startup method provided by this embodiment is shown. For the convenience of description, only the parts related to this embodiment are shown, and the details are as follows:

[0022] The system includes a PCIE expansion chip and multiple function chips connected with the PCIE expansion chip. Due to the limitation of the microprocessor interface, the interface can be extended through the PCIE expansion chip.

[0023] In step 101, when starting up, initialize the PCIE expansion chip and multiple function chips.

Abstract

The invention provides a starting up method and system, and belongs to the field of starting up. The starting up system includes a PCIE extension chip and a plurality of multifunctional chips connected to the PCIE extension chip. The starting up method includes: initializing the PCIE extension chip and the plurality of multifunctional chips; writing a register state value of the PCIE extension chip and register state values of the plurality of multifunctional chips in firmware; reading the register state value of the PCIE extension chip and the register state values of the plurality of multifunctional chips which are saved in the firmware while starting up again, and allowing the PCIE extension chip and the plurality of multifunctional chips to restore to the working state of the last starting up. The starting up method and system can avoid dead halt during starting up.

Description

technical field [0001] The invention belongs to the field of starting up, and in particular relates to a starting up method and system. Background technique [0002] At present, each time the device is turned on, the firmware is initialized first, and then the operating system is entered, and the chip is personalized according to the chip type. Due to the unstable design of the PCIE expansion chip, when the power is turned on, the register status value of the PCIE expansion chip and the register status values ​​​​of multiple function chips connected to it are different after each initialization in the firmware initialization phase, which often leads to Boot crash problem. [0003] To sum up, since the above-mentioned prior art needs to perform firmware initialization each time the device is powered on, the problem that the system is prone to crash when the device is powered on is caused. Contents of the invention [0004] The invention provides a booting method and syste...
